Abstract (en)
[origin: EP2565679A1] According to one embodiment, a nuclear medicine imaging apparatus includes a counting information collection unit (520), a determination unit (522), and a discarding unit (523). The counting information collection unit (520) is configured to collect counting information including detection time of a gamma ray from a counting result output by a detector for counting light derived from a gamma ray, and to store the counting information in a buffer (521). The determination unit (522) is configured to determine whether the volume of the counting information stored in the buffer (521) exceeds a threshold. The discarding unit (523) is configured to, in a case that the determination unit (522) determines that the volume exceeds the threshold, intermittently discards, in chronological order, counting information whose detection time is within longer duration than predetermined duration used for generating two pieces of counting information obtained by counting pair annihilation gamma rays nearly coincidentally as coincidence counting information among the counting information collected from the detector.
